Porcelain slab countertops are becoming an increasingly popular design solution. Porcelain slab is also used in showers, fireplaces, and anywhere you want to make a BIG impression. Here is everything you need to know about porcelain slab.

Pros of Porcelain Slab  

Wall Applications
For wall applications, porcelain slab is very affordable compared to natural stone. Porcelain slab offers a perfect book match and continuous vein options while looking leagues better than other manmade options like quartz or cultured marble.

Exterior Use & Heat Resistance
Because porcelain slabs are waterproof, heatproof, and virtually stain proof, you can use them in applications where you wouldn’t use quartz such as fireplaces, exteriors walls or outdoor kitchens and BBQs.


Stain Resistant
Porcelain offers more stain resistance than all other alternatives. Substances like tomato sauce, turmeric, wine, and soda never discolor your porcelain countertops like they do on marble, granite, or quartz. The surface of porcelain is completely impervious to common foods and chemicals that can damage other materials! Unlike quartz and natural stone, porcelain’s stain resistance is inherent to the material. Other materials use chemical sealers that wear out over time and may even leach into your family’s food!



Easy to Clean & Chef Friendly
Germaphobes can take solace in knowing that porcelain slab can be disinfected with common household cleaners such as bleach or lysol without damaging the finish. Porcelain is an extremely sanitary surface. Porcelain slabs are also scorch-proof! Where quartz counters can melt and natural stone’s chemical sealers can discolor, porcelain counters can take a pan directly out of the broiler without damage. In fact, porcelain countertops are the only countertop option that allows you to use sub-slab induction cooktops for a truly modern and seamless look!



Installation Costs

Because you can cover so much area all at once with large porcelain slabs, it’s a common misconception that it will be cheaper to install than standard sized tiles. The truth is, the precision and specialized tools required for proper slab installation means that you’ll almost always spend a little more to install than standard tile.

Exposed Edges
An aesthetic drawback to porcelain slab is that the image does not run through the thickness of the slab. For designers who want a traditional bullnose edge or want to avoid exposed edges such as when using an undermount sink, this is a finer detail where porcelain slab is lacking. Designing with mitered edges and overmount sinks are ways to avoid these design drawbacks. If you don’t mind the discontinuation of the veining and pattern when seen from the edge of the sink, porcelain slabs offer enormous advantages over alternative natural/man-made surfaces.

Porcelain slabs come in a wide-variety of colors, patterns, and finishes limited only by your imagination. Porcelain surfaces are maintenance free, virtually lifeproof, and potentially healthier for indoor-use. It’s no wonder why porcelain slab has become the go-to material in 2024!
